A heat dissipation device, comprising:

a heat spreader having a first plate and a second plate, wherein the first plate and the second plate are connected to form a receiving space therebetween, and the receiving space is defined with a heated area;
a first capillary material provided on either or both of the first plate and the second plate and located in the heated area;
at least one heat pipe having a cavity in communication with the receiving space, wherein the heat pipe has an end connected to the heat spreader and an opposite end located outside the heat spreader and closed;
a second capillary material provided on an inner wall of the heat pipe;
at least one fiber bundle of an elongated shape, wherein the fiber bundle has a portion located in the receiving space and another portion extending into the cavity, the portion of the fiber bundle that is located in the receiving space is provided on either or both of the first plate and the second plate and is in contact with the first capillary material, and the portion of the fiber bundle that extends into the cavity is in contact with the second capillary material on the inner wall of the heat pipe;
and
a working fluid in the receiving space and the cavity.
